GRAINING-TOOL.

Application filed August 30, 1913.

To all whom it may concern Be it known that I, THOMAS J. MoEL- HENIE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Graining-Tools, (Case B) of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to tools for use in producing imitation graining and is of that type where a ribbed pad is drawn and rocked over the surface to be grained.

One of the objects of the invention is to provide a tool in a form adapted to produce grains closely representing that of natural wood.

Another object is to provide such tool in a form which shall enable the graining.

of narrow surfaces, like the depressed portions around a raised door panel, for example, and will give such narrow portions the appearance of a continuation of th broader surface.

The invention is hereinafter more fully explained and its essential characteristics set out in the claims.

My graining tool is well adapted for embodiment in a structure of the type described and claimed in Patent No. 983,627, granted February 7 1911 to The Ohio Varnish Company as assignee of James B. Lamb, and such an embodiment is shown in the drawings hereof.

In the drawing, Figure 1 is a perspective view of the graining tool embodying my invention; Fig. 2 is a development of the pad thereof; Fig. 3 is a cross section of the tool upon the line 3-3 of Fig. 2.

As shown in the drawing, 1 indicates the body of the tool, 2 the operating handle, and 3 the graining pad. The tool has a curved lower surface on which the pad is mounted so that the tool may be conveniently rocked and simultaneously drawn over the surface being grained. In this operation the operators fingers may conveniently straddle the knob 2 and the fingers rest on Specification of Letters Patent.

the concave surface of the tool against the ends of it.

The form of pad 3 is clearly shown in Fig. 2. It consists of segments of concentric ribs, the ribs being struck about a center which is off of the pad altogether, being located adjacent to one corner thereof.-

These ribs are designated 4 in the drawing and the spaces between them 5. The pad and ribs may conveniently be made of soft rubber.

By swinging the ribs 4 about a center which is entirely off of the pad, the ribs take a form which, near one end of the pad, start approximately parallel with the length of the pad, while, near the other end, they start transversely of the length and nearer crosswise than lengthwise. The pad surface may be described as being an eccentric zone of a series of concentric ribs.

When a tool having the pad described is drawn and rocked over a surface, a grain closely imitative of that of natural wood, particularly oak. is produced. By making the tool in this form I am not only enabled to make it narrow, so as to get into crowded or narrow spaces,but when the tool is used in such narrow space, as for example at the depressed edge of a panel it produces the kind of grain which is usually present in natural wood adjacent to the edge of a board. Accordingly the edge portion of a panel grained with this tool seems a natural continuation of the graining of the broader surface, as effected by such a tool as shown in the pat ent to Lamb referred to.

Having thus described my invention, what I claimris:

1. In a graining tool. the combination of a body having a curved surface and a pad thereon having a series of concentric ribs struck about a center adjacent to the corner of the pad. whereby the figure made bv the right and left edges of the tool is different and the appearance of repetitions bv adja cent applications of the tool is avoided.

2. In a graining tool, the combination of a narrow bodvhaving a curved under sur face and a pad thereon having a series of concentric ribs, the common centerof Which In testimony whereof, I hereunto affix my is gut ofhthe central transacting planefi th; signature in the presence of two Witnesses. 0 y, W ereb'y the ribs start at one e ge o t the pad in a direction approximately 1ongi- V THOMAS MCELHENIE' tudinal thereof While at the other edge they \Vitnesses extend in a direction approximately trans- ALBERTH.
